As the Trump presidency approaches its 100th day, NPR News is launching the initiative, “A Nation Engaged,” to help foster conversation on the topic of “Power & the Presidency.”

Today on AirTalk, we’ll look at the use of executive orders, particularly in the Trump and Obama administrations.

Guests:
